Paper could be basis for inexpensive diagnostic devices

Paper is known for its ability to absorb liquids, making it ideal for products such as paper towels. But by modifying the underlying network of cellulose fibers, etching off surface 'fluff' and applying a thin chemical coating, researchers have created a new type of paper that repels a wide variety of liquids - including water and oil.

Diamonds, nanotubes find common ground in graphene

What may be the ultimate heat sink is only possible because of yet another astounding capability of graphene. The one-atom-thick form of carbon can act as a go-between that allows vertically aligned carbon nanotubes to grow on nearly anything, including diamonds.

Shape-shifting nanoparticles flip from sphere to net in response to tumor signal

Scientists at the University of California, San Diego, have designed tiny spherical particles to float easily through the bloodstream after injection, then assemble into a durable scaffold within diseased tissue. An enzyme produced by a specific type of tumor can trigger the transformation of the spheres into netlike structures that accumulate at the site of a cancer.
